Flatpak is a system for building, distributing, and running sandboxed desktop applications on Linux.
It’s distribution independent package format and the main contributor is Fedora project team. The Flatpak framework is adopted by most of the major Linux distributions.
It provides a sandbox (isolated) environment to run the app and it doesn’t impact either other apps and distribution core packages.
This is the new stable series, ending the 1.3.x series. The major changes since the 1.2.x is the improved I/O use for system-installed applications, and the new format for pre-configured remotes.
